Key Features of LINK-PP LS-DW3910-80I 10G SFP+
LINK-PP LS-DW3910-80I provides 10GBASE-DWDM transmission over single-mode fiber spans up to 80km on a 100GHz grid spacing. Built in a hot-pluggable form factor with a duplex LC interface, it operates across an industrial temperature range of -40°C to +85°C while supporting real-time digital diagnostic monitoring.
LINK-PP LS-DW3910-80I 10G SFP+ Optical Module
This DWDM optical transceiver utilizes a hot-pluggable SFP+ footprint powered by a single +3.3V supply rail. Fully compliant with the SFP+ MSA, the form factor allows hot-swapping directly into operational host cages.
LS-DW3910-80I: 10 Gbps Connectivity for Edge Data Center Interconnects
Line-rate throughput scales up to 10.7Gbps to provide direct 10GBASE-DWDM transport between edge data center locations. This consistent line speed handles continuous data exchange between regional switching nodes.
LS-DW3910-80I Module with DWDM Technology for Fiber Efficiency
Dense wavelength division multiplexing splits transmission onto a strict 100GHz grid spacing. Multiple independent data streams share an existing single-mode line to multiply overall fiber carrying capacity.
LS-DW3910-80I Module with 1546.12nm Wavelength
Emission frequency aligns fixedly at the ITU Channel C39 optical wavelength of 1546.12nm. The cooled transmitter holds this exact optical channel steady to prevent crosstalk into neighboring grid bands.
LS-DW3910-80I Module Supporting 80km Transmission
Long-span optical reach extends up to 80km over standard single-mode fiber. An APD photodetector amplifies weakened inbound light to ensure clean signal reception over extended physical distances.
LS-DW3910-80I Module with Duplex LC Interface
The duplex LC interface establishes optical connectivity across standard single-mode patch cables. Dedicated transmit and receive ports isolate bidirectional optical signals to minimize optical back-reflection.
LS-DW3910-80I Module with DDM for Real-Time Monitoring
Digital diagnostic monitoring reports key operational parameters through the module's 2-wire serial interface. System administrators can continuously read laser bias current, module temperature, supply voltage, and optical power.

Yes. The transceiver is hot-pluggable and can be installed or removed while a compatible router or switch is powered on. Other ports remain unaffected, but traffic on the specific port will stop during the change; ensure redundancy or use a maintenance window for critical links. by LINK-PP Technical Support
Yes. The module is industrial-grade and rated for -40°C to +85°C, suitable for outdoor LTE cabinets with large temperature swings. Keep the module’s case temperature within this range for reliable operation. by LINK-PP Technical Support
Yes. The module supports up to 80km over single-mode fiber, so a 75km link is within its rated reach. Ensure the total link loss, including connectors, splices, and any MUX insertion loss, remains within the module’s optical budget; verify the actual link loss before deployment. by LINK-PP Technical Support
Yes. The module operates on DWDM channel C39 at 1546.12nm, following the standard 100 GHz ITU-T G.694.1 grid. It can be added to a compatible 100GHz DWDM MUX/DEMUX when the C39 channel port is available. by LINK-PP Technical Support
